Synthesis and application of Tamarind Triazine glutamic acid (TTGA) resin

A novel bio-based resin, Tamarind Triazine Glutamic Acid (TTGA), was synthesized through the chemical modification of tamarind seed polysaccharide with triazine and glutamic acid moieties. This study aims to develop a sustainable and eco-friendly resin with potential applications in water treatment, metal ion adsorption and biomedical fields. The resin was characterized using Fourier Transform Infrared (FTIR) spectroscopy. Its ion-exchange capacity, thermal stability and adsorption performance for heavy metals (Fe²⁺, Zn²⁺, Cu²⁺, Pb²⁺, Cd²⁺ and Cr³⁺) were evaluated. The TTGA resin demonstrated promising properties, underscoring its utility as a biodegradable and functional alternative to synthetic resins. Industrial effluent containing heavy metal ions can be selectively separated using TTGA resin. The distribution coefficient (Kd) of metal ions at various pH values was investigated using the batch equilibration method. Investigations were conducted into the effects of adsorbent dosage, treatment duration and pH on the removal of heavy metal ions from industrial effluent. The resin can be repeatedly regenerated and is adaptable to continuous processes.
